Kunststoffe - Schlagzähe Polystyrol (PS-I)-Formmassen - Teil 1: Bezeichnungssystem und Basis für Spezifikationen (ISO 2897-1:1997)

In diesem Teil von ISO 2897 wird ein Bezeichnungssystem für thermoplastische, schlagzähe PS-I-Formmassen festgelegt, das als Grundlage für Spezifikationen dienen kann. PS-I-Formmasse-Typen werden mit Hilfe eines Einteilungssystems voneinander unterschieden, das auf geeigneten Wertebereichen der kennzeichnenden Eigenschaften: a) Vicat-Erweichungstemperatur, b) Schmelze-Massefließrate (MFR), c) Izod-Schlagzähigkeit, d) Biegemodul und Informationen über vorgesehene Anwendung und/oder Verarbeitungsverfahren, wichtige Eigenschaften, Additive und Farbstoffe beruht.

Plastiques - Polystyrenes résistants au choc (PS-I) pour moulage et extrusion - Partie 1: Systeme de désignation et base de spécification (ISO 2897-1:1997)

La présente partie de l'ISO 2897 établit un système de désignation des matériaux thermoplastiques polystyrène résistants au choc (PS-I), qui peut être utilisé comme base pour les spécifications. Les types de plastiques polystyrène résistants au choc sont différenciés les uns des autres par un système de classification basé sur des niveaux appropriés de propriétés de désignation : a) température de ramollissement Vicat ; b) indice de fluidité ; c) résistance au choc Izod ; d) module de flexion ; et sur des informations concernant l'application prévue et/ou la méthode de mise en oeuvre, les propriétés importantes, les additifs et les colorants. La présente partie de l'ISO 2897 est applicable à tous les plastiques polystyrènes résistants au choc présentant un système polymère à deux phases dans lequel la phase continue est constituée par du polystyrène et/ou du copolymère de styrène et du styrène substitué d'alcoyle, et la phase élastomérique dispersée a pour base le butadiène. Elle s'applique aux matériaux prêts à l'emploi normal, non modifiés ou modifiés par des colorants, additifs, charges, etc. La présente partie de HSO 2897 ne s'applique pas aux matériaux extensibles. Le fait que des matériaux aient la même désignation n'implique pas qu'ils présentent nécessairement les mêmes performances. La présente partie de l'ISO 2897 ne comporte pas de données sur la conception, la performance ou les conditions de mise en oeuvre qui peuvent être exigées pour spécifier un matériau pour une application et/ou une méthode de mise en oeuvre particulière. Si de telles caractéristiques additionnelles sont nécessaires, elles doivent être déterminées conformément aux méthodes d'essai prescrites dans l'ISO 2897-2, si appropriée. Afin de prescrire un matériau thermoplastique pour une application particulière ou d'assurer une méthode de mise en oeuvre reproductible, des exigences additionnelles peuvent être codées dans le bloc de données 5 (voir article 3, alinéa d'introducti

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
llnternational Standard IS0 2897-l was prepared by Technical Committee
ISOR’C 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This second edition cancels and replaces the first edition (IS0 2897-l :1990),
the text of which has been brought into accordance with the standard SC 9
frame text.
IS0 2897 consists of the following parts, under the general title Plastics -

INTERNATIONAL STANDARD o Iso IS0 2897-l :1997(E)
Plastics - Impact-resistant polystyrene (PSI) moulding and
extrusion materials -
Part 1:
Designation system and basis for specifications
1 Scope
1.1 This part of IS0 2897 establishes a system of designation for impact-resistant polystyrene (PSI)
thermoplastic materials, which may be used as the basis for specifications.
1.2 The types of impact-resistant polystyrene plastic are differentiated from each other by a classification system
based on appropriate levels of the designator-y properties
a) Vicat softening temperature
b) melt flow rate
c) lzod impact strength
d) flexural modulus
and on information about the intended application and/or method of processing, important properties, additives and
colourants.
1.3 This part of IS0 2897 is applicable to all impact-resistant polystyrene plastics with a two-phase polymer
system comprised of a continuous phase, consisting of polystyrene and/or a copolymer of styrene with an alkyl-
substituted styrene, and a dispersed elastomeric phase based on butadiene.
It applies to materials ready for normal use, unmodified or modified by colourants, additives, fillers, etc.
This part of IS0 2897 does not apply to expandable materials.
1.4 It is not intended to imply that materials having the same designation give necessarily the same performance.
This part of IS0 2897 does not provide engineering data, performance data or data on processing conditions which
may be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they shall be determined in accordance with the test methods specified in
part 2 of this International Standard, if suitable.
